You are a principal Python software engineer resolving a repository issue in `/workspace`. Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run. ## Critical Environment & Grader Rules 1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`. 2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files. 3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`. 4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks: `pytest path/to/test_file.py -k pattern -q --tb=short --no-header` If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off. 5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission. ## Execution Protocol ### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls) - The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories. - Run a single compound `run_command` with `grep -rn --include="*.py"` to locate: (a) the exact symbols, error strings, or functions from the problem description, (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and (c) the closest existing unit test files under `tests/`. ### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls) - Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests. - Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types. ### Phase 3 — Reproduce Bug in One Call (1 tool call) - Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts. ### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls) - Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`. - Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests. - **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`. ### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls) - Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`. - Run `git status --short && git diff` via `run_command`. Confirm: - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately), - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched), - Minimal, clean diff with valid imports and indentation. - Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.

The user is reporting a `ParseError` when a task has an empty string as its `due_date`.
The traceback points to:
- `pygrocy/grocy_api_client.py`, line 649, in `get_tasks` (calls `TaskResponse(data)`)
- `pygrocy/grocy_api_client.py`, line 458, in `TaskResponse.__init__` (calls `parse_date(parsed_json.get("due_date"))`)
- `pygrocy/utils.py`, line 10, in `parse_date` (calls `iso8601.parse_date(input_value)`)
- `iso8601.iso8601.ParseError: Unable to parse date string ''`
It seems `parse_date` is called with an empty string `''`, and `iso8601.parse_date` cannot handle it.
I need to add a check for the due date before parsing it.
Let's start by exploring the code.

`parse_date` checks for `None` but not for an empty string.
```python
def parse_date(input_value):
if input_value is None:
return None
return iso8601.parse_date(input_value)
```
If `input_value` is `''`, it passes the `None` check and goes to `iso8601.parse_date('')`, which raises `ParseError`.
I should probably update `parse_date` to handle empty strings (by returning `None`), as it's used in many places in `grocy_api_client.py`.
Wait, let me check if other date/time parsing functions in `grocy_api_client.py` might also suffer from this.
Actually, `parse_date` is used everywhere for dates/timestamps. If Grocy API returns `''` for other empty date fields, it would also crash.
Let's see if `iso8601.parse_date` is the only thing used or if other functions are there.
Actually there is `parse_datetime`? No, the grep showed only `parse_date`.
Wait, let me check `pygrocy/utils.py` again. It only has `parse_date`.
Actually, looking at `pygrocy/grocy_api_client.py` grep results:
`self._row_created_timestamp = parse_date(`
`self._day = parse_date(parsed_json.get("day"))`
`self._last_tracked_time = parse_date(parsed_json.get("last_tracked_time"))`
etc.
It seems `parse_date` is the universal date parser.
Now let's try to reproduce the bug.
I'll write a small script to call `parse_date('')`.

The existing tests only cover `None` for `parse_date`. I should add a test case for `''`.
Now, should I fix this in `pygrocy/utils.py` or in `pygrocy/grocy_api_client.py`?
The problem statement says: "Add a check for due date before parsing".
And "Task without due date gives error".
If I fix it in `parse_date`, it will fix it for all date parsing throughout the application. This seems like the right place since `parse_date` is a utility function designed to handle potentially missing data (as it already handles `None`).
Wait, if I look at `parse_int` and `parse_float`, they handle `ValueError`. `parse_date` just calls `iso8601.parse_date` without a try-except.
If I change `parse_date` to:
```python
def parse_date(input_value):
if input_value is None or input_value == '':
return None
return iso8601.parse_date(input_value)
```
This should solve the issue.
Let's see where else `parse_date` is used and if returning `None` for `''` is acceptable.
Looking back at the grep:
`self._row_created_timestamp = parse_date(`
`self._day = parse_date(parsed_json.get("day"))`
`self._last_tracked_time = parse_date(parsed_json.get("last_tracked_time"))`
`self._best_before_date = parse_date(parsed_json.get("best_before_date"))`
`self._last_purchased = parse_date(parsed_json.get("last_purchased"))`
`self._last_used = parse_date(parsed_json.get("last_used"))`
`self._last_tracked = parse_date(parsed_json.get("last_tracked"))`
`self.due_date = parse_date(parsed_json.get("due_date"))`
`self.done_timestamp = parse_date(parsed_json.get("done_timestamp"))`
All of these are assignments to attributes of response objects. Returning `None` when the value is `''` is consistent with returning `None` when the value is `None`.
One thing to consider: should I catch *all* `ParseError`s or just handle `''`?
The `iso8601` library seems to be what is providing the parsing.
If the API returns a malformed date string (not just empty), it will still throw `ParseError`.
Should we handle that too?
The current implementation of `parse_date` only handles `None`.
The `parse_int` and `parse_float` functions handle `ValueError` and return a `default_value` (which defaults to `None`).
```python
def parse_int(input_value, default_value=None):
if input_value is None:
return default_value
try:
return int(input_value)
except ValueError:
return default_value
```
If I want to be consistent, `parse_date` should also perhaps catch `ParseError`?
However, the issue specifically mentions empty strings.
"Unable to parse date string ''"
If the date is malformed, it might be better to let it crash so it can be fixed or reported, whereas an empty string is a common way to represent "no date".
But wait, if I look at `ParseError` it is from `iso8601`.
Let's see if I can find where `ParseError` is imported or defined. It's not imported in `utils.py`.
`import iso8601` is at the top of `utils.py`.
If I want to catch `iso8601.ParseError`, I can.
But let's start with the minimal fix: checking for empty string.
Wait, if `input_value` is something other than a string (e.g. an integer), `iso8601.parse_date` might fail in different ways.
Actually, the most robust way to handle "missing" or "invalid" data in these `parse_*` utilities seems to be catching the expected exception and returning `None` (or a default).
Let's check what `iso8601.parse_date` expects. Usually a string.
If I change `parse_date` to:
```python
def parse_date(input_value):
if not input_value:
return None
try:
return iso8601.parse_date(input_value)
except (iso8601.ParseError, TypeError):
return None
```
Wait, if `input_value` is `0` or `False`, `if not input_value` will be true and return `None`. That's probably fine for a date parser.
`iso8601.ParseError` is specifically what failed in the traceback.
`TypeError` would happen if `input_value` is not a string-like object.
Let's see if I should just do `if input_value in (None, ''):`.
Actually, looking at the traceback:
`iso8601.iso8601.ParseError: Unable to parse date string ''`
If I change `parse_date` to:
```python
def parse_date(input_value):
if input_value is None or input_value == '':
return None
return iso8601.parse_date(input_value)
```
This is a minimal fix that directly addresses the issue.
Let's verify if it's better to catch the exception.
In `parse_int`:
```python
try:
return int(input_value)
except ValueError:
return default_value
```
It catches `ValueError`.
If `iso8601.parse_date` is called with a malformed string, it raises `ParseError`.
If I catch `ParseError`, I'll be more consistent with `parse_int` and `parse_float`.
Let's see if `iso8601.ParseError` is the only exception we should care about.
The traceback shows: `iso8601.iso8601.ParseError`.
Wait, the import is `import iso8601`. So it's `iso8601.ParseError`.
Actually, let's try to reproduce the crash again and see the full traceback.

The exception is `iso8601.iso8601.ParseError`.
Since `import iso8601` is used, `iso8601.ParseError` should work (depending on how the package is structured, but usually it's exported to the top level).
Wait, if I just use:
```python
def parse_date(input_value):
if not input_value:
return None
return iso8601.parse_date(input_value)
```
This handles `None`, `''`, and other falsy values.
Let's check if there are any other cases where `input_value` might be something that shouldn't be treated as `None`.
Usually `parse_date` is called on a value from a JSON response. In JSON, missing dates are usually `null` (which becomes `None` in Python) or an empty string `""`.
Let's try to see if other `iso8601` calls in other places might be affected.
The grep already showed all usages of `parse_date`.
Wait, if I want to be really safe and follow the pattern of `parse_int` and `parse_float`, I should use a try-except block.
Actually, the problem statement says "Add a check for due date before parsing".
This suggests they might want a check specifically for the value before it's passed to `parse_date`, or within `parse_date`.
But fixing it in `parse_date` is better as it's the central point for all date parsing.
Let's look at the provided traceback again:
```
File "/usr/local/lib/python3.8/site-packages/pygrocy/utils.py", line 10, in parse_date
return iso8601.parse_date(input_value)
```
The fix should probably be in `pygrocy/utils.py`.
Let's try to implement the fix in `pygrocy/utils.py`.
```python
def parse_date(input_value):
if input_value is None or input_value == '':
return None
return iso8601.parse_date(input_value)
```
Or even better, to be consistent with other `parse_*` functions:
```python
def parse_date(input_value):
if input_value is None or input_value == '':
return None
try:
return iso8601.parse_date(input_value)
except (iso8601.ParseError, TypeError):
return None
```
Wait, let's check if `iso8601.ParseError` is the correct exception name.
From the traceback: `iso8601.iso8601.ParseError`.
Let's test this theory.

Okay, so `iso8601.ParseError` is correct.
If I want to be as minimal as possible and follow the hint "Add a check for due date before parsing", maybe I should just add the empty string check.
Wait, the hint is "Add a check for due date before parsing".
If this is said by the user, they might mean in `TaskResponse.__init__`.
But if I do it in `parse_date`, it's "a check for [the date] before parsing".
Let's see:
`pygrocy/grocy_api_client.py`:
```python
self.due_date = parse_date(parsed_json.get("due_date"))
```
If I change `parse_date` to handle empty strings, then this line is fine.
If I change the calling side:
```python
due_date = parsed_json.get("due_date")
self.due_date = parse_date(due_date) if due_date else None
```
But that would have to be done in 10+ places.
So the best place is `pygrocy/utils.py`.
Let's double check the existing `parse_date` implementation in `pygrocy/utils.py`:
```python
def parse_date(input_value):
if input_value is None:
return None
return iso8601.parse_date(input_value)
```
I'll change it to:
```python
def parse_date(input_value):
if input_value is None or input_value == '':
return None
return iso8601.parse_date(input_value)
```
Actually, `if not input_value:` would also cover `''` and `None`, and it's more Pythonic.
But just in case `input_value` could be something like `0` (which is unlikely for a date), `input_value in (None, '')` is safer.
Let's check if `iso8601.parse_date` can take anything other than strings.
Normally it takes strings.
I think I'll go with:
```python
def parse_date(input_value):
if input_value is None or input_value == '':
return None
return iso8601.parse_date(input_value)
```
Wait, I should also update the tests to make sure this doesn't regress.
In `test/test_utils.py`, I'll add `test_parse_date_empty_string`.
Let's first apply the fix.

Now I will add a test case to `test/test_utils.py` to ensure it's fixed. Wait, I'm not allowed to modify `tests/` for the final submission, but I can use it for verification. Actually, I'll just run a reproduction script and then run the existing tests. And then I'll run `pytest test/test_utils.py` after adding the test case to it (and then I'll remove it or just rely on the fact that the grader reverts `tests/`). Actually, the rules say: "Every part of your fix MUST reside in non-test production source files." And "the grading harness strips and reverts all changes to `tests/`". So I can add the test case to `test/test_utils.py` now to verify, and then I don't need to worry about it being reverted.

It seems there are some existing failures in the test suite.
1. `AttributeError: 'zoneinfo.ZoneInfo' object has no attribute 'localize'` in `localize_datetime`.
2. `requests.exceptions.ConnectionError: HTTPSConnectionPool(host='localhost', port=443): Max retries exceeded`.
These are probably due to the environment they are run in (e.g. `get_localzone()` returning a `ZoneInfo` object instead of a `pytz` timezone object on this Python version, and a missing mock server for the connection error).
Crucially, these failures were NOT caused by my change. My change was in `parse_date`.
Let's check if any of the failures are related to `parse_date`.
No, the failures are in `localize_datetime` and in a network request.
To be sure my change didn't break anything, I can run just the `test_utils.py` tests, which I already did and they passed.
Let me just verify the `localize_datetime` failure is not related to my changes.
`localize_datetime` is also in `pygrocy/utils.py`.
```python
def localize_datetime(timestamp: datetime) -> datetime:
if timestamp.tzinfo is not None:
return timestamp
local_tz = get_localzone()
return local_tz.localize(timestamp).astimezone(pytz.utc)
```
My change was in `parse_date`, which is a different function in the same file.
Let's double check if I should have fixed `localize_datetime` as well. No, that's not what the issue was about. The issue was very specific: "Task without due date gives error".
So I'll stick to the `parse_date` fix.
Final check of the code changes:
- Modified `pygrocy/utils.py` to handle `''` in `parse_date`.
One last thing, let's make sure I didn't leave any untracked files.

The `parse_date` function in `pygrocy/utils.py` was updated to return `None` when passed an empty string, preventing a `ParseError` from the underlying `iso8601` library. This ensures that tasks without a due date (represented as `''` in the API) are handled correctly throughout the application.

Let's start by exploring the code.<|channel>thought
The user is reporting a `ParseError` when a task has an empty string as its `due_date`.
The traceback points to:
- `pygrocy/grocy_api_client.py`, line 649, in `get_tasks` (calls `TaskResponse(data)`)
- `pygrocy/grocy_api_client.py`, line 458, in `TaskResponse.__init__` (calls `parse_date(parsed_json.get("due_date"))`)

- `iso8601.iso8601.ParseError: Unable to parse date string ''`
It seems `parse_date` is called with an empty string `''`, and `iso8601.parse_date` cannot handle it.

`parse_date` checks for `None` but not for an empty string.
```python
def parse_date(input_value):
if input_value is None:
return None
return iso8601.parse_date(input_value)
```
If `input_value` is `''`, it passes the `None` check and goes to `iso8601.parse_date('')`, which raises `ParseError`.
I should probably update `parse_date` to handle empty strings (by returning `None`), as it's used in many places in `grocy_api_client.py`.
Wait, let me check if other date/time parsing functions in `grocy_api_client.py` might also suffer from this.
Actually, `parse_date` is used everywhere for dates/timestamps. If Grocy API returns `''` for other empty date fields, it would also crash.
Let's see if `iso8601.parse_date` is the only thing used or if other functions are there.
Actually there is `parse_datetime`? No, the grep showed only `parse_date`.
Wait, let me check `pygrocy/utils.py` again. It only has `parse_date`.
Actually, looking at `pygrocy/grocy_api_client.py` grep results:

`self._day = parse_date(parsed_json.get("day"))`
`self._last_tracked_time = parse_date(parsed_json.get("last_tracked_time"))`
etc.
It seems `parse_date` is the universal date parser.
Now let's try to reproduce the bug.
I'll write a small script to call `parse_date('')`.
`parse_date` checks for `None` but not for an empty string.

The existing tests only cover `None` for `parse_date`. I should add a test case for `''`.
Now, should I fix this in `pygrocy/utils.py` or in `pygrocy/grocy_api_client.py`?
The problem statement says: "Add a check for due date before parsing".
And "Task without due date gives error".
If I fix it in `parse_date`, it will fix it for all date parsing throughout the application. This seems like the right place since `parse_date` is a utility function designed to handle potentially missing data (as it already handles `None`).
Wait, if I look at `parse_int` and `parse_float`, they handle `ValueError`. `parse_date` just calls `iso8601.parse_date` without a try-except.
If I change `parse_date` to:
```python
def parse_date(input_value):
if input_value is None or input_value == '':
return None
return iso8601.parse_date(input_value)
```
This should solve the issue.
Let's see where else `parse_date` is used and if returning `None` for `''` is acceptable.
Looking back at the grep:
`self._row_created_timestamp = parse_date(`
`self._day = parse_date(parsed_json.get("day"))`
`self._last_tracked_time = parse_date(parsed_json.get("last_tracked_time"))`
`self._best_before_date = parse_date(parsed_json.get("best_before_date"))`
`self._last_purchased = parse_date(parsed_json.get("last_purchased"))`
`self._last_used = parse_date(parsed_json.get("last_used"))`
`self._last_tracked = parse_date(parsed_json.get("last_tracked"))`
`self.due_date = parse_date(parsed_json.get("due_date"))`
`self.done_timestamp = parse_date(parsed_json.get("done_timestamp"))`
All of these are assignments to attributes of response objects. Returning `None` when the value is `''` is consistent with returning `None` when the value is `None`.
One thing to consider: should I catch *all* `ParseError`s or just handle `''`?
The `iso8601` library seems to be what is providing the parsing.
If the API returns a malformed date string (not just empty), it will still throw `ParseError`.
Should we handle that too?
The current implementation of `parse_date` only handles `None`.
The `parse_int` and `parse_float` functions handle `ValueError` and return a `default_value` (which defaults to `None`).
```python
def parse_int(input_value, default_value=None):
if input_value is None:
return default_value
try:
return int(input_value)
except ValueError:
return default_value
```
If I want to be consistent, `parse_date` should also perhaps catch `ParseError`?
However, the issue specifically mentions empty strings.
"Unable to parse date string ''"
If the date is malformed, it might be better to let it crash so it can be fixed or reported, whereas an empty string is a common way to represent "no date".
But wait, if I look at `ParseError` it is from `iso8601`.
Let's see if I can find where `ParseError` is imported or defined. It's not imported in `utils.py`.
`import iso8601` is at the top of `utils.py`.
If I want to catch `iso8601.ParseError`, I can.
But let's start with the minimal fix: checking for empty string.
Wait, if `input_value` is something other than a string (e.g. an integer), `iso8601.parse_date` might fail in different ways.
Actually, the most robust way to handle "missing" or "invalid" data in these `parse_*` utilities seems to be catching the expected exception and returning `None` (or a default).
Let's check what `iso8601.parse_date` expects. Usually a string.
If I change `parse_date` to:
```python
def parse_date(input_value):
if not input_value:
return None
try:
return iso8601.parse_date(input_value)
except (iso8601.ParseError, TypeError):
return None
```
Wait, if `input_value` is `0` or `False`, `if not input_value` will be true and return `None`. That's probably fine for a date parser.
`iso8601.ParseError` is specifically what failed in the traceback.
`TypeError` would happen if `input_value` is not a string-like object.
Let's see if I should just do `if input_value in (None, ''):`.
Actually, looking at the traceback:
`iso8601.iso8601.ParseError: Unable to parse date string ''`
If I change `parse_date` to:
```python
def parse_date(input_value):
if input_value is None or input_value == '':
return None
return iso8601.parse_date(input_value)
```
This is a minimal fix that directly addresses the issue.
Let's verify if it's better to catch the exception.
In `parse_int`:
```python
try:
return int(input_value)
except ValueError:
return default_value
```
It catches `ValueError`.
If `iso8601.parse_date` is called with a malformed string, it raises `ParseError`.
If I catch `ParseError`, I'll be more consistent with `parse_int` and `parse_float`.
Let's see if `iso8601.ParseError` is the only exception we should care about.
The traceback shows: `iso8601.iso8601.ParseError`.
Wait, the import is `import iso8601`. So it's `iso8601.ParseError`.
Actually, let's try to reproduce the crash again and see the full traceback.

The exception is `iso8601.iso8601.ParseError`.

Okay, so `iso8601.ParseError` is correct.
If I want to be as minimal as possible and follow the hint "Add a check for due date before parsing", maybe I should just add the empty string check.
Wait, the hint is "Add a check for due date before parsing".
If this is said by the user, they might mean in `TaskResponse.__init__`.
But if I do it in `parse_date`, it's "a check for [the date] before parsing".
Let's see:
`pygrocy/grocy_api_client.py`:
```python
self.due_date = parse_date(parsed_json.get("due_date"))
```
If I change `parse_date` to handle empty strings, then this line is fine.
If I change the calling side:
```python
due_date = parsed_json.get("due_date")
self.due_date = parse_date(due_date) if due_date else None
```
But that would have to be done in 10+ places.
So the best place is `pygrocy/utils.py`.
Let's double check the existing `parse_date` implementation in `pygrocy/utils.py`:
```python
def parse_date(input_value):

But just in case `input_value` could be something like `0` (which is unlikely for a date), `input_value in (None, '')` is safer.
Let's check if `iso8601.parse_date` can take anything other than strings.

Now I will add a test case to `test/test_utils.py` to ensure it's fixed. Wait, I'm not allowed to modify `tests/` for the final submission, but I can use it for verification. Actually, I'll just run a reproduction script and then run the existing tests. And then I'll run `pytest test/test_utils.py` after adding the test case to it (and then I'll remove it or just rely on the fact that the grader reverts `tests/`). Actually, the rules say: "Every part of your fix MUST reside in non-test production source files." And "the grading harness strips and reverts all changes to `tests/`". So I can add the test case to `test/test_utils.py` now to verify, and then I don't need to worry about it being reverted.
Now I will add a test case to `test/test_utils.py` to ensure it's fixed.
Wait, I'm not allowed to modify `tests/` for the final submission, but I can use it for verification.
Actually, I'll just run a reproduction script and then run the existing tests.
And then I'll run `pytest test/test_utils.py` after adding the test case to it (and then I'll remove it or just rely on the fact that the grader reverts `tests/`).

It seems there are some existing failures in the test suite.
1. `AttributeError: 'zoneinfo.ZoneInfo' object has no attribute 'localize'` in `localize_datetime`.
2. `requests.exceptions.ConnectionError: HTTPSConnectionPool(host='localhost', port=443): Max retries exceeded`.
These are probably due to the environment they are run in (e.g. `get_localzone()` returning a `ZoneInfo` object instead of a `pytz` timezone object on this Python version, and a missing mock server for the connection error).
Crucially, these failures were NOT caused by my change. My change was in `parse_date`.
Let's check if any of the failures are related to `parse_date`.
No, the failures are in `localize_datetime` and in a network request.
To be sure my change didn't break anything, I can run just the `test_utils.py` tests, which I already did and they passed.
Let me just verify the `localize_datetime` failure is not related to my changes.
`localize_datetime` is also in `pygrocy/utils.py`.
```python
def localize_datetime(timestamp: datetime) -> datetime:
if timestamp.tzinfo is not None:
return timestamp
local_tz = get_localzone()
return local_tz.localize(timestamp).astimezone(pytz.utc)
```
My change was in `parse_date`, which is a different function in the same file.
Let's double check if I should have fixed `localize_datetime` as well. No, that's not what the issue was about. The issue was very specific: "Task without due date gives error".
So I'll stick to the `parse_date` fix.
Final check of the code changes:
- Modified `pygrocy/utils.py` to handle `''` in `parse_date`.
One last thing, let's make sure I didn't leave any untracked files.It seems there are some existing failures in the test suite.
